Description

AUDIO AMP CLASS D 44W TQFN-36
The MAX98400A/MAX98400B Class D amplifiers provide high-performance, thermally efficient amplifier solutions. The MAX98400A delivers 2x20W into 8I loads or 1x40W into a 4I load. The MAX98400B delivers 2x12W into 8I loads. An integrated limiting circuit prevents output clipping distortion, protects small speakers from transient volt- ages, and reduces power dissipation. A thermal-foldback feature can be enabled to automati- cally reduce the output power at above a junction tem- perature of +120NC. Traditional thermal protection is also available in addition to robust overcurrent protection. The ICs operate from a single 8V to 28V supply and provide a high 67dB PSRR, eliminating the need for a regulated power supply. They offer up to 90% efficiency from a 12V supply. Filterless modulation allows the ICs to pass EN55022B EMI limits with 1m cables using only a low-cost ferrite bead and small-value capacitor on each output. Both devices feature eight digitally controlled gain settings. Comprehensive click-and-pop reduction circuitry mini- mizes noise coming into and out of shutdown. The MAX98400A/MAX98400B are available in 36-pin and 24-pin TQFN packages, respectively, and are speci- fied over the -40NC to +85NC temperature range.
